Bing Ads
✅ Editing UTM parameters at the campaign or ad group level does not trigger an ad review and does not affect your optimization score. Make these changes as soon as possible.
⚠️ Tracking templates at different levels override each other. Bing uses the most specific level: ad > ad group > campaign > account. If you're setting tracking templates or Final URL suffixes at the ad level, they will override anything set higher up — and Klar won't track those ads. Always check for ad-level overrides.
Parameters
New setup (no existing UTM parameters)
Bing's UTM auto-tagging makes this simple. Add this to your account-wide and ad group tracking templates:
{lpurl}?klar_source=bing&klar_adid={AdId}
Then enable UTM auto-tagging in your account settings. Bing will automatically append utm_source, utm_medium, utm_campaign, and utm_term for you.
Existing UTM parameters
If you already have UTM parameters in your tracking template, make sure these are either already present or appended:
utm_source=bing OR utm_medium=bing
utm_campaign={Campaign}
utm_term={AdGroup}
utm_content={keyword:default}
klar_source=bing
klar_adid={AdId}
Example:
Below is an example of how adding the required parameters to existing parameters looks like with the added parameters being bold:
{lpurl}?utm_source=bing&utm_medium=cpc&utm_campaign={Campaign}&utm_term={AdGroup}&utm_content={keyword:default}&klar_source=bing&klar_adid={AdId}
Implementation
Three steps to complete: enable UTM auto-tagging, set the account-wide tracking template, and set the ad group tracking template.

Go to Settings → Account level options
Check the box next to Add UTM tags to my destination URLs
Select Keep my existing tags and add any that are missing
Step 2 — Set the account-wide tracking template
Go to Settings → Account level options
Paste the parameters from above into the Tracking template field
Step 3 — Set the ad group tracking template
Go to Ad groups and select all ad groups
Click Edit → Change URL options
In the popup, set Action to

Best practices
Add the Tracking template column to your ad group column preset so you can quickly see which ad groups have parameters applied.
Check for ad-level overrides. If any ads have their own tracking templates or Final URL suffixes, they will override the ad group and account settings — and those ads won't be tracked by Klar. Remove or align them.
Apply to all ad groups, not just active ones. Paused ad groups can be reactivated or duplicated at any time.
